FreeBSD developer Poul-Henning Kamp (PHK) happens to run a tier-1 NTP server, intended only for use by ISPs' main servers in Denmark, and specifically not intended for individual client connections, not to mention client connections from anywhere else in the world. He offers this service pro bono to ISPs. Unfortunately, D-Link has decided to abuse the open nature of the NTP protocol and has actually hard-coded PHK's server hostname in the firmware of several of their home network products. Since contacting D-Link yielded no results, PHK went public.
